Title:
POWER AMPLIFICATION CIRCUIT AND POWER AMPLIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286492
Kind Code:
A1
Abstract:
A power amplification circuit (10) comprises: an external input terminal (111); an external output terminal (101); power amplifiers (11-14); a transformer (21) having an input-side coil (211) and an output-side coil (212); and a transmission line (31). The external input terminal (111) is connected to an input terminal (11a) of the power amplifier (11) and an input terminal (12a) of the power amplifier (12). An output terminal (11b) of the power amplifier (11) is connected to an input terminal (13a) of the power amplifier (13) and an input terminal (14a) of the power amplifier (14). An output terminal (13b) of the power amplifier (13) is connected to one end (211a) of the input-side coil (211). An output terminal (14b) of the power amplifier (14) is connected to the other end (211b) of the input-side coil (211). The external output terminal (101) is connected to one end (212a) of the output-side coil (212). An output terminal (12b) of the power amplifier (12) is connected to the other end (212b) of the output-side coil (212) through the transmission line (31).
